<p><strong>Error in Weather_Shield_Weather_Station.ino where &ldquo;windspeedmph&rdquo; reads &ldquo;0.0&rdquo;</strong></p>
<p>If your code is reading &ldquo;windspeedmph=0.0&rdquo;, this is due to an error in the code not updating &ldquo;<em>windspeedmph</em>&rdquo;. For more information, try reading the issue <a href="https://github.com/sparkfun/Weather_Shield/issues/24" rel="nofollow" >https://github.com/sparkfun/Weather_Shield/issues/24</a>. There is a Pull Request to fix this issue. By downloading the <em>Weather_Shield_Weather_Station.ino</em> code, it will update <em>windspeedmph</em>.</p>
<p><strong>Humidity, Temperature, and Barometric Pressure Not Reading?</strong></p>
<p>If you are seeing this as the output in your serial monitor, make sure that you are connected sufficiently to the shield:</p>
<pre><code>$,winddir=113,windspeedmph=0.0,windgustmph=0.0,windgustdir=0,windspdmph_avg2m=0.0,winddir_avg2m=86,windgustmph_10m=0.0,windgustdir_10m=0,humidity=998.0,tempf=-1766.2,rainin=0.00,dailyrainin=0.00,pressure=-999.00,batt_lvl=16.32,light_lvl=3.21,#,
</code></pre>
<p>This is due to the connection to one of the sensors that is using I2C. I2C is sensitive to loose connections and it will not function correctly if the connections are not secure. Keep in mind this setup did not include the wind meter and rain gauge.</p>
<p><strong>Issues using the Software Serial with GPS?</strong></p>
<p>Having issues connecting to the weather shield but you are not using the ATmega328P microcontroller with an Arduino bootloader? The issue is probably due to your connections. There are two ways to connect to your GPS using the UARTs looking at the Eagle files. There is either the hardware UART pins (pin 0 or 1) or the software serial UART pins (pins 4 and 5). The weather shield was designed with the Arduino Uno footprint. There can be some compatibility issues if you move to other packages like the Arduino Mega. You would need to reroute the pins for the GPS if you were using software serial. Not all the pins are compatible for software serial on the Arduino Mega => <a href="https://www.arduino.cc/en/Reference/SoftwareSerial" rel="nofollow" >https://www.arduino.cc/en/Reference/SoftwareSerial</a> . If you redefine the software serial pins and reroute the location of the pins that the shield is using, you shouldn’t have any issues when using the software serial pins. You can also use the hardware serial UART pins on the Arduino Mega but I don’t recommend doing that. You can have issues when uploading code to the Arduino Mega since it uses the same serial UART pins.</p>
<p>Try looking at this comment to reroute the pins and redefine the pins <a href="https://learn.sparkfun.com/tutorials/arduino-shields/discuss#comment-54cc220cce395ff2068b4568" rel="nofollow" >https://learn.sparkfun.com/tutorials/arduino-shields/discuss#comment-54cc220cce395ff2068b4568</a> .</p>
<p><strong>BAS16 Diodes</strong></p>
<p>If anyone is wondering why the two BAS16 diodes are connected in series with the respective power supply terminals and an I/O pin between the diodes, the circuit was placed on the board for static protection by an engineer. This was just in case static electricity built up with the weather meter when it is out in the field or if long wires were used between the sensors and Arduino. This would safely protect the Arduino&rsquo;s I/O pins in case there was discharge.</p>
<p>If you search online for &ldquo;static protection diode,&rdquo; you will find a few application circuits and an explanation. There are even packages manufactured for static protection. We just happen to use diodes already in our shelves for the application circuit.</p>Customer #485825 on DEV-12081 - SparkFun Weather ShieldCustomer #485825urn:uuid:53a80b15-39f6-4794-e046-f0f2f16f2a1a2016-02-24T07:47:21-07:00<p>Any suggestion how to connect this shields Analog pins to Pi2 via MCP3008?

I am new to Arduino and lost some hours with the light sensor on the weather shield. I had strange readings when I put on a LED-headlight for testing purposes. The value on A1 went up but came down again to initial low light value without a reason. You guess what happend.. the sensor is so fast, it reacts on the fast flashing of the 1W LED headlight. After putting a 10uF tantalum condensator from A1 to ground, everything works fine. I guess you may encounter wrong values also from flashing of 50Hz or 60Hz lighting. So it turned out, the board is fine, all the sensors seem to deliver correct values.

I wonder if someone has used this shield with the Intel Edison board.
I connected this shield to the Edison and the the 2 IC2 addresses (0x40 &amp; 0x60) are not recognised by the board.
The same shield work quite well with the UNO and MEGA boards.
I want to build a robust weather information server and this shield could fit quite well if I am make it to work.
Thanks.

Unfortunately the fix is probably curing the symptoms and not the real cause. To get it to work, I had it read an extra byte, i.e. 4 instead of 3 and then discarded the first byte. Now the pressure is calculated properly.</p>
<p>In addition, the temperature appears to be read correctly if you read 6 bytes and throw away the first 4. The conclusion is that the TwoWIre class is ignoring which byte to read and always starts at byte 0.</p>AllenKempe on DEV-12081 - SparkFun Weather ShieldAllenKempeurn:uuid:e7410f46-ad79-82ec-61e7-55d071079be42014-09-07T15:36:56-06:00<p><strong>Weather Shield and pcDuino</strong>
I have had mixed success using the Weather Shield on a pcDuino 3s. I have loaded the latest kernel (20140721) and the latest lUbuntu (20140430). I also have loaded the pcDuino with Qt version 4.8.6 and Qwt 6.1.0.</p>
<p>My first attempts to duplicate the output of the Weather_Shield_with_GPS sketch running on an Arduino Uno resulted in many discrepancies.
* I could not get the serial output to work. Several web queries leads me to believe that the SoftwareSerial library does not work on the pcDuino. So, I turned the switch on the Weather Shield to route the GPS output to UART2. This did not work at first until I obtained a copy of the setuart2 program that can be used to turn the UART on or off. Now, I was able to receive and process the GPS data.</p>
<ul>
<li><p>While the HTU21D module&rsquo;s humidity and temperature seem to be working properly, the same could not be said for the MPL3115A2 pressure and temperature. I have not yet determined why this the case. It should be noted that the HTU21D readings returned are skewed by the heat given off by the pcDuino board.</p></li>
<li><p>The readings returned for battery level and light level were wrong. The light level never seemed to change. I finally determined that there were two problems. First, the value of /proc/adc1 which should be the light level always seems to be 63 no matter how much light is shining on the light sensor. However, I discovered that if the unused AD0 pin is grounded (I don&rsquo;t have the optional wind and rain sensors), then the value of adc1 (/proc/adc1) would change. However, the program still didn&rsquo;t display a good value for light_lvl. This turned out to be because the ad0 and AD01 pins are only 6 bits resolution instead of 12 like the others. So, the value returned has to be shifted: change the get_light_level function line where the light sensor is read from:
float light_sensor = analogRead(LIGHT);
<em>to</em>
float light_sensor = (analogRead(LIGHT)&lt;&lt;6) | 0x37;</p></li>
</ul>
<p>I have developed a Qt graphical application using the Weather Shield and would be glad to share my code. And if anybody knows why the MPL3115A2 doesn&rsquo;t work, I&rsquo;d appreciate it.</p>EorEquis on DEV-12081 - SparkFun Weather ShieldEorEquisurn:uuid:83b62605-6218-99f3-4a7f-43fa345b155d2014-08-24T11:02:42-06:00<p>Does your station use the rain and win meters as well?</p>

I was using this in conjunction with the XBee WiFi along with, essentially, the sample code from the weather shield hookup guide and the Internet Datalogging with XBee WiFi guide. And while this all makes complete sense and each is a great resource on their own it tends to put a little stress on the memory of an Uno R3. Once we trimmed the fat on memory usage (specifically RAM usage) the stack has been running great!</p>
<p>One last note&hellip;I found that stacking the two shields (Uno then XBee then Weather - if you put Weather before XBee the light sensor is kinda pointless) causes the temperature sensor to give higher than actual readings. Its amazing how much heat the XBee gives off. I &ldquo;solved&rdquo; this by simply moving the XBee to an Explorer Regulated breakout.</p>bdicken on DEV-12081 - SparkFun Weather Shieldbdickenurn:uuid:5f6a1449-271e-66a0-57e5-a050a2cef9022014-08-16T19:44:46-06:00<p>my email is B504now@yahoo.com - if you send me an email, i will send you the code tomorrow when I get home.

I have the weather shield and the XBee shield and I can either get the weather stuff to work (displaying on the serial console) or the wifi to work (sending some dummy data to Sparkfun Data) but it I try to get them both working it seems like the communication with the XBee gets trashed. The hardware in all cases remains the same (Arduino + XBee + Weather) - all I am doing is changing the sketch. I even have a version of s sketch that has the XBee working and all I have to do is just include wire.h and it break; don&rsquo;t even do anything with it just add that one line and the communication dies.

<p>I know Sparkfun is updating the weather board but I like the shield better. Having an Uno underneath is less of a burden and it does make the whole process of development simpler. My suggestion would be to add a second shield. Take the current Xbee shield (which I love) and add LIPO charging circuit, an I2C RTC, and an SD slot. This would take the current shield and make it easily standalone. Xbee for wireless, LIPO for remote power, the clock and shield to store data if the wireless link drops. The Weather board will end up pretty dense pretty fast and having 3 boards isn&rsquo;t a big deal.</p>

I was planning on using this in an environmentally stable enclosure (no light, controlled temp, weather proof, dust proof, etc). It would be great if this board had the sensor connect via connectors, so that I can locate the sensors outside, while the shield, arduino and other electronics are safely inside. Looks like I&rsquo;ll have to build my own version and use this board to prototype the software with.</p>
<p>Another thing that I noticed, the weather shield and the ProtoShield (DEV-07914) both do not fit on the Arduino Uno, Arduino Ethernet Shield, or the Arduino Yun. They all make contact with either the ethernet connector metal case, the USB-A port, or the USB-B port (on the Uno) and cannot be fully seated on the headers. I presume metal around the ports are all grounded and would therefor ground this shield and the ProtoShield (leds, resistors, and switches). Not sure which Arduinos the shields will fit on.</p>
<p>EDIT: (SOLVED) I inserted an additional set of stackable headers (PRT-11417) between the Arduino Board and the Weather Shield. Additionally, I&rsquo;m going to use the weather shield as is, since it has the pressure sensor, rain and wind connectors, etc already, and they will work within the enclosure. The on board humidity and temp will give me data for temp within the enclosure. Then, I&rsquo;m going to add an additional board on top that will have a RJ-11 connector that I&rsquo;ll connect additional temp and humidity (for inside and outside of my greenhouse) via I2C to multiple HTU21D Humidity Sensor Breakout (SEN-12064) boards.</p>Ripsnorter on DEV-12081 - SparkFun Weather ShieldRipsnorterurn:uuid:f17485aa-c802-e478-e4b8-3d4cd3bd94862014-03-22T20:11:37-06:00<p>Thanks your post gave me the key piece of information that I needed to get the Yun working with the wind, rain, pressure and humidity sensors. I used a soft I2C library( https://code.google.com/p/rtoslibs/downloads/detail?name=DigitalIO20130221.zip ) so interrupts are no longer an issue and ported the libraries that Sparkfun provide for each of the sensors. Anyway incase someone finds this useful I have posted the code here:
https://bitbucket.org/craigspry/weatherstation/
This has only had a very quick test, 5 minutes on my bench, so there are probably lots of bugs lurking in the code.

There are some things you can do to reduce sensitivity to noise. The long wires pick up noise from lightening etc.

Out of the box they will not work but with some simple changes you can get most of the features working.</p>
<p>I was looking to record temperature, and humidity, and I now have this working with the Yun and the weather shield.</p>
<p>As noted here the two wire interface on the Yun is on D2&amp;D3 as opposed to the UNO which is on A4&amp;A5. The temperature, humidity and pressure sensors on the shield are wired to A4/A5. So for now I have jumped A4 to D2 and A5 to D3.</p>
<p>Second, the weather shield wants power via VIN which it regulates to 3.3V for the pressure, temperature humidity sensors etc. Unloaded there is 5V present on VIN on the Yun but as soon as you plug in the shield it goes away. Simple solution is to jump 5V to VIN (I am powering Yun via USB). Note there is a warning about VIN on the YUN spec sheet.</p>
<p>I now have the example code running, but I removed all of the code related to wind, and rain because of the jumps I made above (Wind and Rain are on D2 and D3).</p>Захария Стургин on DEV-12081 - SparkFun Weather ShieldЗахария Стургинurn:uuid:90d57a15-724f-b211-7ca6-74eccdec157f2014-03-07T19:23:36-07:00<p>Just got my weather shield, but forgot to order headers. (In my impatience) I slapped on what I had, forgoing VIN, and pins 8 and 9. It took me a visit to the schematic to figure out why I was getting bogus values without VIN connected, but now that it&rsquo;s working I&rsquo;ve still run into some interesting issues with the example sketch on the Leonardo:</p>
<ol>
<li>The serial seems unreliable, starting indeterminately. I think this is a known issue with the serial reset on the Leonardo.</li>
<li>When serial data is being output, everything looks in order, except for the rain sensor. It just keeps racking up values despite being disconnected.</li>
<li>After the anaeometer spins for the first time, serial data is only output when the aneometer is still spinning. Otherwise it stops sending.</li>
</ol>
<p>Any suggestions?</p>
<p>Edit: Guessing that this is an interrupt problem, further inspection of the datasheet reveals that the anaeometer is supposed to close a switch once per revoluion, but checking it on a multimeter it&rsquo;s actually a normally closed contact that opens when the magnet passes. Did I get a deffective/different anaeometer, or is this just an interrupt issue?</p>
<p>Edit 2: I isolated the issue to interrutps being fired whenever working with the I²C bus to read the barometer, etc. The Leonardo uses pins 2 &amp; 3 for I²C, so an interrupt gets fired every time data is sent. As a work around in software, you can detach the interrupts for the weather sensors before using I²C data, and reattach them when done.</p>Nate on DEV-12081 - SparkFun Weather ShieldNateurn:uuid:9e765c19-dcaf-16c6-8e7d-4c3b0be043512014-02-26T15:18:29-07:00<p>Hmm, this is very interesting.

Very short duration drops, like less than 100 nanoseconds. Changed the interrupt handler in the sample code to confirm the pin is low. Seems to work better now. Maybe the pull-up just isn&rsquo;t enough at times? I found the same problem with the wind speed by the way. Taped it in position and still saw occasional clicks. Much less of an issue there I think since it takes so many to get even 1 mph of wind speed.</p>Ripsnorter on DEV-12081 - SparkFun Weather ShieldRipsnorterurn:uuid:d42d6c8a-5508-e6c4-882e-b7128e0248c52014-02-18T04:20:45-07:00<p>I&rsquo;m attempting to use a soft I2C library(https://code.google.com/p/rtoslibs/downloads/list) to get this shield to work with the Yun, but I&rsquo;m noticing some odd behaviour. Here what I have tried so far. Firstly I got the the MPL3115A2 breakout board working with this library, basically converted the sample sketch with an Arduino Duemilanove. Then once that worked I got the humidity sensor to work and did a simple sketch that read from both sensors and plugged in the weather shield and it worked, much to my surprise. I also tested this with a Uno.</p>
<p>Then I repeated the same process with the Yun, the MPL3115A2 breakout board worked but the weather shield did not, with Simple humidity/pressure sketch or the weather shield sketch. The other odd thing I noticed that the rain and the wind interrupt had to be swapped to read correctly.</p>
<p>So can anyone here shed some light on why this may be so?</p>
<p>I can share the code if anyone is interested, once I&rsquo;ve tidied it up.</p>
<p>*UPDATE: I got the Soft I2C to work with the weather shield and Yun when I plugged the 5V pin from the Yun to the Vin pin on the Yun, not too sure why this works because when I measured it they were about the same voltage. I will wire up the wind and rain sensors when I have time and report back if they work.</p>c.fowler on DEV-12081 - SparkFun Weather Shieldc.fowlerurn:uuid:133ccbf9-3e40-3c06-de95-ea7615c5501a2014-02-12T18:17:35-07:00<p>I suggest putting it top most so it is more exposed to the environment.

It appears that MPL3115A2.cpp does not take into account the 2’s complement nature of negative numbers used by the device; (see Application Note). The following shows additions to readTemp() which appear to fix this:</p>
<p>…</p>
<pre><code> word foo = 0;
bool negSign = false;
if(msb &gt; 0x7F)
{
foo = ~((msb &lt;&lt; 8) + lsb) + 1; //2’s complement
msb = foo &gt;&gt; 8;
lsb = foo &amp; 0x00F0;
negSign = true;
}
// The least significant bytes l_altitude and l_temp are 4-bit,
// fractional values, so you must cast the calulation in (float),
// shift the value over 4 spots to the right and divide by 16 (since
// there are 16 values in 4-bits).
float templsb = (lsb&gt;&gt;4)/16.0; //temp, fraction of a degree
float temperature = (float)(msb + templsb);
if (negSign)
temperature = 0 - temperature;
return(temperature);
}
</code></pre>
<p>This affects pressures also, if there is a negative value.</p>
<p>Note that -999 results indicate a timeout. In the cpp, the timeout values have been increased versus other examples.</p>
<p>Also, there was question about the Ethernet shield. It’s fairly easy to combine this code with the Arduino BarometriPressureWebServer example. But, keep in mind that the Wiznet W5100 is quite hot and very close. It added about 10F at room temperature.</p>

This is much closer than the pressure value reported yet is not corrected to known weather pressure

<p>For anybody else using this with the EtherTen, you can cut out a slot in the weather shield where the RJ45 jack protrudes. This cuts the traces to the dedicated I2C pins (for R3 arduinos) and the serial wires (for GPS). You don&rsquo;t need the I2C pins with the EtherTen, and if you need to use GPS, you can add the serial lines back with a couple wires. This allows the weather shield to seat onto the EtherTen without extra spacers. The only negative is that it places the sensors about 1cm closer to the warm chips on the EtherTen. Also, it voids your warranty and removes the SparkFun logo, so I guess those are negatives too ;)</p>CanaDoc on DEV-12081 - SparkFun Weather ShieldCanaDocurn:uuid:f3b794cf-b5c5-453b-55e9-6b5a5f69f85f2013-12-14T11:57:08-07:00<p>While what you say is true, it also applies to any enclosure - a black box with a lightpipe/fiber optic would certainly suffer from solar heat gain as well - at least with a clear enclosure you could add a foil shield to reflect the solar radiation and hopefully mitigate this gain.</p>johnc2 on DEV-12081 - SparkFun Weather Shieldjohnc2urn:uuid:9a208725-1f5b-6e56-9ea2-83284cc9ce4d2013-12-12T15:04:31-07:00<p>Thanks for the research&hellip;much appreciated.</p>M-Short on DEV-12081 - SparkFun Weather ShieldM-Shorturn:uuid:5c59005d-d7a7-44c0-a6eb-30314b9fe25c2013-12-12T14:49:26-07:00<p>I started testing this unit, and I was able to get the Yun to output data from the example code. But, you can&rsquo;t use the rain or wind sensors. The rain and wind sensors are on D2 and D3 because those are the interrupt pins on the ATMega328. While they are also the interrupt pins on the ATMega32U4, they are also the I2C pins on the ATMega32U4. Because the sensors on the board are I2C, this means there is conflict with the Rain/Wind sensors. The logical resolution would be to connect the rain/wind sensors to the ATMega32U4s interrupts, but, the ATMega32U4 only has them on D2, D3, and D7 (and the hardware serial lines which are not available on the YUN). In other words there just aren&rsquo;t enough free interrupt pins to use the rain/wind sensors. If you aren&rsquo;t using them it should work though. Keep in mind that the shield will short A4/A5 and D2/D3. Also with the Yun the Ethernet jack is tall enough that no shield will fit on it well. I would just get an extra set of stackable headers.</p>BKR2 on DEV-12081 - SparkFun Weather ShieldBKR2urn:uuid:22a07c81-45a0-0469-fc54-3397afb7fc912013-12-11T15:54:52-07:00<p>Hardware wise it might work then, but what about conflicts with the bridge library.

The HTU21D datasheet recommends this pattern for ventilation slits, along with clearing copper layers (which has been done, based on the picture of rear of this pcb).</p>
<p>Btw, its not 100% clear based on the pcb picture, but it seems D6 may not be grounded (due to the gnd fill being pinched off by the through-hole connector). However, D6 is for neg. volt. protection on &lsquo;RAIN&rsquo; and not critical to operation.</p>
